Specification Lettem-2etent "A plication-med Uctober 30, wrz. 1 Serial No. 199,265.

To'all whom it may concern: a

Be it known that '1, WILLIAM H. HOWARD, a citizen of the UnitedStates, and "resident of Port Chester, in the county of Westchester' and State of New York, have invented certain new and useful Improvements in Atomizing Devices, of which the "following is a specification.

This invention relates to improvements in atomizing devices,*the object being to provide a device that will efi'ectively atomize or spray a disinfectant, dye or any other element that requires atomizi'ng. My invention is not limited to any particular'use 'but can be employed wherever atomizing is de-' sir-able or necessary.

To carry my invention into practice, I employ a rapidly rotating disk upon which the element to be atomized or sprayed is dropped, said element being cast from the peripheral edge of the disk by centrifugal force, a jet of under pressure being preferably employed to increase the atomizing or spraying effect.

I will now proceed to describe my invention, the details of'which will be pointed out in the claims, reference being had to the accompanying drawings, wherein Figure l isa vertical sectional View of an embodiment of my invention'partly in elevation;

Fig. 2 is a top plan view thereof; and

Fig. 3 is a sectional plan view, the section being taken on a line 33 in' Fig. 1.

As herein embodied, my invention consists of a disk 4 carried by a rotatable shaft 5, said shaft being in this instance tubular in order that pipes or ducts 6 and 7 can be passed therethrough for the introduction of a heating medium into the chamber 8 of the disk 4 and to convey the heating medium from said chamber. The duct 6, in this instance, conveys the heating medium, steam or hot air, to the chamber 8 while the duct 7 is the outlet for said heating medium, the source of supply being omitted.

The shaft 5 can be rotated by any suitable mechanism but I have herein indicated a steam or compressed air turbine 9 located within a chamber 10 carried by the stand ard 11. Steam or air is conveyed to the turbine by a duct 12, the duct 13 being for the exhaust (see Fig.

Adjacent the disk 4 I located recessed disks, members 14 and 15, forming a chamber, having an annular peripheral opemng 16 whichcanbe made narrower or wider as conditions may require. 'It will be seen that the opening or slot 16, formed by locating the surfaces 17 and 18 of'the disks 14 and 15 slightlyaway from each other, is angularly inc ined and is directed toward the peripheral edge 19 of the under rotatable disk 4, said opening being in communication with the chamber 20 formed by placing the re cesses of the disks 14 and 15 together, as shown. The disks 14 and 15 are carried by a pipe or duct 21 threadedas at 22, the hubs 23 and 24 of the disks 1'4 "and 15 being threaded to engage the threads 22, jamnuts 25 and 26 being em loyed to secure the said disks in position. The disk 14 is further provided with a duct 27 for the admission of air under pressure.

The disks 14 and '15, which when assembled, constitute a chamber having an annular opening, are rendered adjustable toward .or away from each other-in order thatthe width of the opening or slot 16' can-be varied to regulate the jet of air or other fluid passing theret'hrough. The size of the opening 16 can be varied by rotating the upper disk 14, for instance, upon the threaded'portion 22 ofthe pipe or duct 21 after the jam-nut 25 has been loosened.

The lower rotatable chambered disk 4 can be regulated toward or away from the upper chamber, indicated generally by A, by manipulating the adjusting threaded plug 28 which bears against the ball-bearing member 29 carried by the shaft 5. the lower chamber has been adjusted, the lock nut 30 will be set up'tohold the pin in the adjusted position. The lower chain er is made adjustable in order that the spraying efi ect of the air blastyissuing from the slot or orifice 16 can be altered, the closer the disk to the lower disk 15 of the upper chamber 4, the greater will be the spraying efiect of the air blast.

If desirable, the lower rotatable chamber can be heated by steam, hot air or hot water introduced into the space 8 through the duct 6 and exhausted through the duct 7. For some varieties of disinfectant, or other element to be atomized and spread, it might be desirable to heat the same in order to reduce them to a more complete liquid state. For this reason the lower disk is made hollow to form a chamber. The element to be atomized is dropped into the lower disk 4 through the duct 21, while the said disk 4 is rotating,

Eatented meta-.31, sees.

said disk being rotated a jet of steam 01' air under pressure acting upon the turbine 9. The matter dropped upon the disk 4 will be thrown by centrifugal force from the edge 19 of the disk in the form of a spray but to increase the spraying effect and also .to lend more force to the spray, I preferably 'trifugal force only, hence the atomized matter will find its way into the innermost recesses of articles to be sprayed, forinstance, andwill also have a greater range of efliciency wherever employed, due to the fact that it will traverse more space.

What I claim is:

1. In an atomizing device, a rotatable disk, a chamber adjacent thereto provided with an opening directed toward the peripheral edge of said disk, means to introduce air under pressure intosaid chamber, and meansto feed the element to be atomized to said disk. 2. In an atomizing device, a rotatable disk, a chamber adjacent thereto provided with an opening directed towardsaid disk, means to introduce air under pressure into said chamber, means to feedjthe element to be atomized to said disk, and means to adjust the rotatable disk relatively to the opening in said chamber.

3. In an atomizing device, a chambered disk, means to introduce a heating'element into the chamber, means'to rotate the chambered disk, and means to feed the element to-be atomized onto said disk while it is rotating. 1

4. In. an atomizing device, a rotatable disk, means to rotate same, means to feed the element to be atomized onto said disk while means while it is rotating, a chamber adjacent said disk consisting of a plurality of recessed adjustably mounted disks spaced apart at the periphery thereof to form an annular opening, said opening being directed toward the peripheral edge of the rotatable disk, and to introduce air under pressure into said chamber.

6. In an atomizing device, a rotatable disk, means to feed the element to be atomized to said disk while it is rotating, means to direct a stream of a fluid under pressure onto said disk thereby assisting to atom- -ize said element, and means to adjust or vary the size of said stream.

7 In an atomizing device, a rotatable disk, means to rotate same, means to feed the element to be atomized to said disk while it is rotating and means to direct a constant flow of air under relatively high pressure upon the peripheral edge of the disk while it I is rotating. 8.. The method of atomizing, consisting of directing a supply of the element to be atomized upon a rapidly rotating body, and directing a stream of air under relatively high pressure upon said body at an angle relatively to the surface thereof to mingle with the element to be atomized.
